Ansible：无法在同步时从“ansible.playbook.play_context”导入名称“MAGIC_VARIABLE_MAPPING”

Question

尝试运行剧本。

剧本：

- name: copy files between hosts
  hosts: all
  tasks:
  - name: copy file from ubuntu to rocky
    synchronize:
      src: /etc/hosts
      dest: /tmp/hosts
      mode: push
    delegate_to: localhost
  - name: check file
    stat:
      path: /tmp/hosts
    register: statfile
  - debug:
      var: statfile

当我运行剧本时，出现错误：

ERROR! Unexpected Exception, this is probably a bug: cannot import name 'MAGIC_VARIABLE_MAPPING' from 'ansible.playbook.play_context' (/usr/local/lib/python3.10/dist-packages/ansible/playbook/play_context.py)

当我用复制替换同步时，它可以工作

在Ubuntu中，默认情况下/usr/local/lib/python3.*/dist-packages/中没有

dist-packages

shell> cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=24.04
DISTRIB_CODENAME=noble
DISTRIB_DESCRIPTION="Ubuntu 24.04.1 LTS"

shell> tree /usr/local/lib/
/usr/local/lib/
└── python3.12
    └── dist-packages

ansible 模块的默认位置是

/usr/lib/python3/dist-packages/ansible

shell> cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=24.04
DISTRIB_CODENAME=noble
DISTRIB_DESCRIPTION="Ubuntu 24.04.1 LTS"

shell> dpkg -l | grep ansible

shell> ansible --version | grep dist-packages
  ansible python module location = /usr/lib/python3/dist-packages/ansible

shell> find /usr/lib/python3/dist-packages/ansible -name play_context.py
/usr/lib/python3/dist-packages/ansible/playbook/play_context.py

Python虚拟环境中的pip安装位置是

(env) > find /home/admin/env/lib/python3.12/site-packages/ -name play_context.py
/home/admin/env/lib/python3.12/site-packages/ansible/playbook/play_context.py

(env) > python3 -m pip list | grep ansible
